RBNS can occur on certain mornings where one wakes up and the proboscis staring back is visibly larger than the one from the night before. This phenomenon does not occur in any observable pattern but irritants are thought to be cameras and alcohol.
Upon diagnosis, one should treat with full Mr Potatohead mask, if not available large glasses or spending the day indoors is recommended.
Symptoms usually disappear within a day.
